Description

[Detailed Description of the Invention] The present invention relates to a beard debris disposal structure, that is, a cleaning structure, in a rotary electric shaver.

As a method for easily cleaning beard debris with a conventional electric razor, a structure such as that in Publication of Utility Model Publication No. 49-9507 has been proposed. In this proposal, a rotor body is provided that rotates integrally with the inner blade that slides into pressure contact with the outer blade to cut the beard when performing a shaving operation, and rotates integrally with the inner blade during shaving. The cut hair waste is introduced into a separately provided dust collection chamber, and when the shaved hair waste is processed, only the rotor body is rotated independently at high speed, and the hair waste in the cutting chamber is introduced into the dust collection chamber. When the lid for opening and closing the dust collection chamber and the outside of the case is opened, the hair debris accumulated in the dust collection chamber is scattered to the outside of the case. With the above structure, the cut hair waste is accumulated in the dust collection chamber, but some of the hair waste is a part of the skin (stratum corneum) that has been shaved off along with fat and beard from the skin.
The hair debris accumulated in the dust collection chamber hardens over time, so even if the rotor body rotates at high speed and blows air outside the dust collection chamber, the hair debris cannot be removed. It had become impossible to dispose of the particles scattered outside the case. As a method to solve this problem, as shown in FIG.
Normally, when only the inner blade rotates to cut the beard and clean the hair, the rotary blade body 50 engages with the drive unit through the clutch and rotates at high speed, thereby cutting the cutting chamber 53 and the case. 52 Lid body 54 that opens and closes with the outside
By setting the cutting chamber 53 in the open state, hair, fat, and skin (stratum corneum) in the cutting chamber 53 are scattered and discharged from the discharge port 55 while the rotary blade body 50 stirs them. With this structure, it is possible to discharge hair waste, but the direction in which the hair waste is discharged from the hair waste discharge hole formed in the case is in the direction of arrow C in the figure, that is, in the radial direction of the rotary blade 50. On the other hand, since the direction is approximately 45° to 90°, hair particles adhere to the external surface of the case 52 or the outer periphery of the lid 54 due to the influence of static electricity, etc., causing discomfort. Further, it is sufficient that the side wall 56 of the discharge port 55 with respect to the arrow c in the direction in which the beard debris is discharged has the same inclination as the direction of the arrow c, but if the side wall 56 is substantially perpendicular to the arrow c direction, the beard debris from the rotary blade body 50 At the time of discharge,
The beard debris is pressed against the side wall 56, which not only impairs the beard debris discharge effect, but also blocks the discharge port 55, making it impossible to discharge the beard debris.
On the other hand, as described above, if the side wall 56 is made to have the same inclination as the direction of the arrow c, there is a problem in that hair debris will adhere to the external surface as described above.

The present invention eliminates the above-mentioned drawbacks and provides a practical cleaning structure that prevents hair from adhering to the external surface of the outer periphery of the case and enables reliable removal of hair and hair.

The present invention will be explained in detail with reference to the drawings based on one embodiment. FIG. 1 is a partial sectional view showing one embodiment of the present invention. FIG. 2 is a partial cross-sectional view of the hair collecting tray shown in FIG. 1 in which the hair collection plate is rotated and floated to discharge beard debris. FIG. 3 is a side view showing a state in which the case through hole and the pin portion of the hair collecting plate are penetratingly engaged with each other. FIG. 4 is a sectional view taken along the line AA in FIG. 1. Fifth
The figure is a BB sectional view in FIG. 2. FIG. 6 is a sectional view showing the conventional example in the same state as FIG. 5. FIG. 7 is an enlarged view of the discharge port portion in FIG. 5.

In Figure 1, 1 is a case, 2 is the case 1
3 is an outer cutter; 4 is an inner cutter body that rotates in sliding contact with the inner surface of the outer cutter 3; 5 is a motor that supports the inner cutter body 4; This is an inner blade support to which a spring 6 for pressure contact is fixed, and a clutch part 7 is integrally formed at the lower part of the inner blade support. Reference numeral 8 denotes a hair collecting plate, which is rotatably inscribed inside the case 1 at the lower part of the inner blade body 4. Reference numeral 9 denotes a cleaning piece, which has a slight clearance on the inner wall surface of the hair collecting plate 8, and is fitted loosely around the center of the hair collecting plate so as to be freely rotatable. On the upper surface of the cleaning piece 9, there is a convex portion 10 that can be engaged with and disengaged from the clutch 7 that is integrally formed at the lower part of the inner cutter support 5.
are integrally formed. 11 is an outer frame for fixing the outer cutter 3; 12 is a connector fixed to the shaft of the motor 2 and transmits the driving force of the motor 2 to the inner cutter support 5; 13 is an outer frame that rotates around the outer surface of the case 1; A movable ring surrounding the hair collection plate 8 is disposed inside the case 1 as shown in FIGS. 3 to 5.
A pin 14 projecting more integrally passes through a through hole 15 formed in the side wall of the case 1 and engages with the ring 13. Reference numeral 16 designates a discharge port opened in the side wall of the hair collecting plate 8, and reference numeral 18 designates a discharge port opened in the ring 13. Reference numeral 19 denotes a side wall of the discharge ports 16, 17, 18 facing in the direction of rotation of the cleaning piece 9. Reference numeral 20 is integrally formed on the side of the outer end of the discharge port 18 of the ring 13 so as to protrude outward. ) is a convex part for guiding whisker debris that changes the direction of discharge of whisker debris in order to prevent whisker debris from adhering to the outer surface of the case when discharging whisker debris. In the above structure, during normal shaving, the ring 13 and hair collecting plate 8 are positioned as shown in FIGS. 1 and 4, so each outlet 1
6, 17, and 18 do not match. Further, the clutch portion 7 formed at the lower part of the inner blade support 5 does not engage with the convex portion 10 formed on the cleaning piece 9. On the other hand, the through hole 15 opened in the side wall of the case 1 shown in FIG. , is engaged with a stepped portion formed on the inner surface of the ring 13 on the outer surface side of the case 1. The pin 14 is located at the lowest (left end) of the through hole 15 in FIG.
In the case of Fig. 4, the discharge ports 16, 17, and 18 do not coincide, and the second
In the case of FIG. 5, each of the discharge ports 16, 17,
18 are aligned and the hair collecting plate 8 floats along the inclined through hole 15, so that the clutch portion 7
The convex portion 10 engages with the cleaning piece 9, and the cleaning piece 9 rotates together with the inner blade support 5, thereby scattering and discharging hair debris and the like adhering to the inner surface of the hair collecting plate 8 from the discharge ports 16, 17, and 18. Also the fifth
As shown in FIG. 7, the outlet 18 of the ring 13
A center line P connecting the approximate center of the inner blade body 4 and the rotation center of the inner cutter body 4
The angle θ formed by the side wall 19, which is provided to face the beard debris discharge direction C, due to the rotational force of the cleaning piece 9 at each discharge port 16, 17, 18,
Since it is gradually changed so that it is larger on the side and smaller on the side of the ring 13, the direction of the beard debris is gradually changed and changes from the direction of the arrow C to the direction of the center line P. Also, a ring 13 with an open discharge port 18
A convex part 20 for guiding whisker debris is formed on the outer periphery of the beard debris guide for changing the discharge direction for discharging whisker debris, so that the side wall 19 is kept long, so that the direction of discharging whisker debris is gradually changed. This makes it easier to do so and enhances the effect of guiding the direction of beard debris discharge. If the side wall 19 is thin in the radial direction without the above-mentioned convex portion 20, no matter how the angle θ between the side wall 19 and the center line P is changed, the whisker debris will only be discharged in the direction of the arrow C. It is also possible to increase the thickness of each of the ring 13, case 1, and hair collection plate 8 to guide hair debris, but since each part is a resin molded product, this is not possible from the molding conditions and appearance. It cannot be made too thick. Furthermore, increasing the wall thickness also increases costs. This prevents the discharged beard debris from adhering to the outer surface of the case.
Also, as shown in FIG. 7, when the discharge port spans multiple parts such as the ring 13, the case 1, and the hair collecting plate 8,
Exhaust ports 1 are arranged continuously toward the outside.
As 6, 17, and 18 spread out, the pool part disappears in the beard waste discharge direction C, and the discharge port 1
No whisker debris remains on the inside of 6, 17, and 18. Further, even if the side walls 19 of the discharge ports 16, 17, 18 facing the beard waste discharge direction C are sloped,
It may be a curved surface that changes gradually, and if it is a curved surface, the angle θ formed by the center line P and the side wall 19 of each member with respect to the direction C of discharging whisker debris by the cleaning piece 9 should be made larger on the hair collecting plate 8 side ( If the structure is configured such that the size is approximately parallel to the waste discharge direction C) and gradually becomes smaller toward the ring 13 side, the beard waste can be smoothly discharged due to the rotational force and centrifugal force of the cleaning piece 9.
Beard debris is less likely to remain in the areas 6, 17, and 18.

The present invention is constructed as described above, and even if the hair debris contains fat from the skin, the cleaning piece is rotated by the powerful force of the motor to agitate the hair debris and remove the hair debris that has adhered to the inner surface of the hair collecting tray. Remove debris and ensure that it is discharged from the outlet. In addition, since the above-mentioned convex portion for guiding beard debris is formed on the side of the outer end of the ring discharge port, the thickness of the discharge port in the radial direction is increased, increasing the guiding effect in the direction of discharging beard debris. Also, the aforementioned angle θ
is formed smaller on the ring side and larger on the hair collection plate, so the beard debris gradually changes its direction and is finally discharged in the direction of the center line P. Therefore, as shown in FIG. Case 52 in the vicinity
Alternatively, the beard debris is not discharged in the circumferential direction of the outer peripheral surface of the lid 54, so that the beard debris is not deposited on the outer peripheral surfaces of the case 52, the lid 54, etc. Since no residue remains, it is possible to remove beard debris with a single touch without causing discomfort and without touching the beard debris. The direction of rotation of the cleaning piece may be clockwise or counterclockwise, and the shape of the outlet may be determined according to the direction of rotation. Thus, the present invention provides a practical electric shaver cleaning mechanism.
